i have personally not paid much attention to descriptions when searching on matrimony websites. i give more importance to the actual data they provide about themselves, e.g. age/dob, height, profession, education, etc. for a few reasons:
1. when you're searching through thousands of profiles, there is no way to search by description. you can only search by these data elements like height, etc. so no matter what you put in the search, one might not even get to see your profile until you match their search criteria.
2. descriptions are often highly subjective and prone to interpretation in any way the reader wants. words like "homely", "ambitious", "family oriented", "good looking" mean one thing to one person and another to another person. such a subjective identification of yourself does not always work as well as you would expect it to. e.g. i once found a girl's profile where she said "my family is highly educated". when i asked her about her parents and her siblings' education, she told me that about 50% of them had a bachelor's degree.
